  • I imagine there is a fairly hefty cable to an 11kV or higher voltage incomer.  At best it will put some power back into the grid when it is warm and sunny and there are no customers, and take from the grid when it is gloomy and cold.

    Still an improvement over no solar  generation of course, even if all it does is provide power for the restaurant and lights in the toilets, but I cannot help but smile at the way the piece is written. No mention of kilowatts or square metres, the things that would show the design details have been properly considered . Given the mails breathless journalist style, if they had the info it would be ' XX football pitches of panels', or 'saving the emissions of so many power stations'  or something.


     

    Actually the  gridserve website  is equally sparse on the technical details, and looking more closely, they do not yet seem to have any completed projects at all to date, not even a plain solar farm example, so perhaps the jury is out as to if they are a serious player. I suspect given the size of the company,  after all companies house shows accounts exemptions  and the no. of situations vacant, that the business model is to try to pull in investors and then to subcontract the hard work of solving the technical details and doing the tricky sums to another company.



    We know that fairly 'run of the mill'  chargers of say 7kW  need perhaps 50 square metres of panels each in  good weather and maybe ten times that to be useful when not so bright. Does not mean it cannot be done, but  some thousands of square metres of panel area will be needed for the proposed 24 charging points.


    As an aside, a solar power station, say 1 gigawatt, would be 10 000 000 square metres, on a good day  (so 3km by 3km)  Again not impossible, but a serious land area.
